Abstract
A 61 year-old male had a 20-year history of lower leg edema and anemia. The patient was malnourished and laboratory tests revealed anemia and hypoproteinemia. Colonoscopy revealed a fistula between the jejunum and the transverse colon near the splenic flectu.re. It seemed that the anemia and malnutrition were caused by malabsorption due to this fistula. Surgical resection vas performed. At laparotomy, some diverticula were found on the opposite side of the attachment of the small intestine, and one of them formed a jejunocolic fistula. A strong adhesion was found throughout the colon and small intestine. Histologically, the diverticulum was a true diverticulum, and there was an aberration of gastric mucosa, but no ulceration. Therefore, it was considered that this fistula was probably formed as a result of penetration of a jejunal diverticulum. This case is very rare because only one case of penetration of a Meckel's diverticulum has been reported previously in Japan.
